PFF summer fellow Eric Beach and I have been working on what we hope is a comprehensive taxonomy of all the threats to online security and privacy. In our continuing Privacy Solutions Series, we have discussed and will continue to discuss specific threats in more detail and offer tools and methods you can use to protect yourself.

The taxonomy of 21 different threats is organized as a table that indicates the "threat vector" and goal(s) of attackers using each threat. Following the table is a glossary defining each threat and providing links to more information.Threats can come from websites, intermediaries such as an ISP, or from users themselves (e.g. using an easy-to-guess password). The goals range from simply monitoring which (or what type of) websites you access to executing malicious code on your computer.

Please share any comments, criticisms, or suggestions as to other threats or self-help privacy/security management tools that should be added by posting a comment below.
